| 摘 要： | 采用活性Al2O3对高氟区地下水进行降氟处理,研究了活性氧化铝的除氟机理、最佳投放量及影响因素.试验结果表明,300 mL氟化物质量浓度为1.75 mg/L的原水样,投加6 g活性氧化铝时,氟化物质量浓度降到1.0 mg/L以下,且其它各项水质指标也均达到饮用水标准.活性氧化铝在酸性条件下,温度低于26℃,反应20 min时除氟效果最佳.处理后的活性氧化铝可利用明矾、盐酸、硫酸铝作为再生试剂进行再生处理.

| Abstract: | By adopting activated alumina method to reduce fluoride concentration of groundwater in the high fluoride area,the mechanism of removing fluorine,optimum throwing quantity and influencing factors is studied in the paper.The result indicated that fluoride concentration was less than 1 mg/L when 6 g active alumina was put into 300 ml water sample which fluorine concentration was 1.75 mg/L and other water quality parameters also reached drinking water standards.The best treatment effect of activated alumina method was under the acid condition,below 26 ℃ and about 20 minutes reaction time.Activated alumina also can be regenerated by using of alum,hydrochloric acid and aluminum sulfate. |
